SPECIFICATION forming part of Letters Patent No. 412,125, dated October 1, 1889.

Application filed April 29, 1889.

To all whom it may concern.-

Be it known that I, JOHN SGHEIPERS, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Im provement in Pipe-Cleaners, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a sectional coneauger for cleaning stand-pipes and other lines and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a vertical section taken on line I I, Fig. IV, and shows a foul stand-pipe in the course of being cleaned by the auger. Fig. 11 is an enlarged perspective view of the auger. Fig. III is a top view of one of the disk-bits, which are seated on the shank of the instrument and are respectively to each other of a conically-reduced diameter toward the point or forward end of said instrument; and Fig. IV is an end view of the extension transmittal flue of the retort and a detail of the standpipes surmounting the same.

Referring to the drawings, 1 represents the detail of agas-retort, and is the transmittal flue that forms an extension thereof and from which the stand-pipes 3 ascend, that carry the gas win, the condenser, washer, purifier, &c., to the holder.

4 represents the hand-hole in the outer end of the transmittal flue through which the hand 5 of the operator enters to effect the cleaning of the stand-pipes.

6 is the shutter-cap of the man-hole, which, except at such times as the stand-pipes or the retorts are being cleaned or the retort opened out for other purposes, is secured to its seat by the usual clamping-screw bolt 7 and arch 8, the said bolt being turned to its locking position by the hand-wheel 9, and 10 is the deposit of bituminous and other matter that settles very largely in the stand-pipes near their entrance.

11 represents the shank of the auger, which is made of a curvilinear form, so as to facilitate the movement of the tool by the handle 12 when manipulated by the operator.

13 represents a bracket shoulder on said shank, on which is seated the rear one of the curvilinear-faced disk-bits 14. The perfora- Serial No. 308,978- (No model.)

tions 15in the centers of said disks enable them to be slipped in the passage to their seat on the disk-bearing rod 16, which is integral with the shank of the tool, on which rod they are respectively placed in conical succession, said disks being of diverse diameters, that of the widest diameter being seated on the shoulder 13 and the succeeding ones being placed in rotation, each succeeding one, reckoning in their order of attachment, being narrower in diameter than the one immediately preceding,

the one at the forward end or point of the tool being of the smallest diameter.

17 represents spacing sleeve-rings which adjust the distance apart of the disk-bits and provide shoulders against and between which said disks are seated.

18 is a washer that is seated on the disk-V bearing rod that carries the disks immediately in front of the small foremost disk, and 19 is a screw-nut that engages on the terminal screw 20 on the disk-bearer rod and firmly holds said disks in position to their respective seats. Now it will be seen that the diskbits are formed with curvilinear faces, and the foremost ones are of the smallest diameter, so that they may the more readily insinuate themselves within the contracted passage that is frequently nearly choked with the bituminous and other foul deposit. Thus the small advance disks work their .way in ahead, and are followed by disks that are each, respectively, of a little larger diameter than the one in advance thereof. Again, the disks have a curvilinear waving face that effects a gouging worming action that both in creases the incisive penetration of the disks and at the same time clears the track longitudinally along the whole extent of the bore of the cleaning-auger; also, the curvilinear waves of the disks and the arrangement of the increased diameter of each of the succeeding disks in boring to that of its predecessor continuously works down and outward the fouling deposit within the stand-pipes.

hen cleaning stand-pipe fines of either larger or smaller dimensions, the disks are easily removed and others of diameter to suit the dimensions of the flue are attached in their place.

Among the many advantages of the sectional disk-cutters in this auger-cleaner are:

First. The disks, being removable, are interchangeable with other disks of respectively larger or smaller diameter, so as to increase or diminish the size of the augerindefinitely.

Second. The disks when dull are easily removable for sharpening.

Third. The disks provide a deeper workingthread than is attainable in a worm-screw auger.

Fourth. The disks having a more nearly direct incisive movement than is attainable with a worm-screw, they cut more quickly through the deposit and thus remove the same much more rapidly.

Fifth. The sectional disks provide a much more abundant carriage for the deposit that the angers bore from the inside of the standpipes.

Sixth. As the sectional disks cut in more freely, the auger while cleaning is Worked with less labor.

Seventh. The sectional construction of the cleaning anger, with its removable disks, sleeve-rings, and shank, adds greatly to the facility of cleaning, which is an object of consideration in the removal of the adhesive sticky bituminous deposit that chokes the throat of the stand-pipes.

I have shown eight disk-bits in use on the cleaner; but I do not confine myself to that number, for a smaller or larger number may be used without departing from the essential features of the invention.

I claim as my invention 1. In a pipe-cleaner, the combination of the crank-bent shank 11, having a handle 12 at one end and an extension disk-bearer rod 16 at the other end, and the succession of disk cutter bits 14, of diverse diameters, the said disks being secured and spaced on said bearer-rod in respective conical position, the diameter of said disks being reduced toward the point or front of the auger, substantially as described, and for the purpose set forth.

2. In a pipe-cleaner, the combination of the crank-bent shank having a handle at one end, an extension disk-bearer rod at the otherfand a flanged shoulder between said shank proper and said disk-bearer rod, the conically-placed disk-bits of diverse diameters, the said disk being bent into a curvilinear form to provide a biting-grip of the auger when worked, and p the sleeve-rings 17, that are seated on the disk-bearer rod and space apart the respective distance of the disks, the said disks being held totheir seats byawasher and screwnut, which latter engages on the screw terminal or point of the disk-bearer rod, substantially as described, and for the purpose set forth.
